Abstract
UN CONVERTISSEUR ANALOGIQUE-NUMERIQUE SUR MICROPLAQUETTE DE CIRCUITS INTEGRES APPLIQUE UNE APPROCHE PAR APPROXIMATIONS SUCCESSIVES ET UTILISE UN DECODEUR DE COMMUTATION DE RESEAU DE RESISTANCES EN ECHELLE ET DES CONVERTISSEURS NUMERIQUES-ANALOGIQUES COUPLES A UN COMPARATEUR DE PRECISION A PLUSIEURS ENTREES. UNE MEMOIRE FIXE PROGRAMMABLE PERMET DE STOCKER LES INFORMATIONS NECESSAIRES A L'AJUSTEMENT DES CONVERTISSEURS. A L'ORIGINE, CETTE MEMOIRE EST SHUNTEE ET LES MOTS NECESSAIRES A UN AJUSTEMENT PRECIS SONT APPLIQUES EXTERIEUREMENT. UNE FOIS DEFINIS LES MOTS D'AJUSTEMENT CORRECTS, UN CONVERTISSEUR A 13BITS RECOIT SEPTMOTS D'AJUSTEMENT A 7BITS POUR ABOUTIR A UN PRODUIT COMPLETEMENT AJUSTE AU COURS DE LA FABRICATION DES GALETTES.AN ANALOGUE-DIGITAL CONVERTER ON A MICROPLATE OF INTEGRATED CIRCUITS APPLIES A SUCCESSIVE APPROXIMATION AND USES A SCALE RESISTOR NETWORK SWITCHING DECODER AND DIGITAL-ANALOGUE CONVERTERS COUPLED BETWEEN ONE COMPARATOR OF PRECISIONS. A FIXED PROGRAMMABLE MEMORY ALLOWS THE STORAGE OF THE INFORMATION NECESSARY FOR THE ADJUSTMENT OF THE CONVERTERS. ORIGINALLY, THIS MEMORY IS SHUNTE AND THE WORDS NECESSARY FOR A PRECISE ADJUSTMENT ARE APPLIED EXTERNAL. ONCE SETTING THE CORRECT ADJUSTMENT WORDS, A 13BIT CONVERTER RECEIVES SEPTMOTS OF 7BIT ADJUSTMENT TO RESULT IN A COMPLETELY ADJUSTED PRODUCT DURING THE CAKE MANUFACTURING.
